This article illustrates with examples of luminescent sensors that have jumped the gap that separates laboratory research from the instrumentation marketplace. Luminescent chemical sensors occupy a prominent place among the optical devices due to their superb sensitivity combined with the required selectivity that electronic photo-excitation imparts to these devices. Luminescent sensors will be cost-effective if the sensitive tips can be interrogated with a single light source and the emission analyzed with a single filter/detector combination.
